Gravity Test Review Sheet In preparation for the test, students should be able to do the following: 1. Identify, define, compare and contrast the following terms; weight, mass, gravity, matter, Newton, kilogram, velocity, acceleration, distance, time 2. Calculate the following formulas; Distance Velocity Final Velocity 2 s =.5gt V = s/t Vf = gt Label is m Label is m/s Label is m/s Gravity Weight Time 2 g = 2s/t W = mg t = √2s/g 2 Label is m/s Label is N Label is s 3. Compare the gravity of the earth, moon and sun. 4. Interpret data given on a data table involving the variables time and distance. 5. Construct a line graph showing how time affects the distance an object free falls. The graph will require scales, labels, points, a line and a title. 6. Draw prediction lines on the line graph to estimate the values of readings not recorded.
